Get Glowing sans Sun
"Shimmery particles in most bronzers can look aging," says Carmindy. Instead, dust a matte bronzer over your complexion, using a fluffy brush to make the application sheer. Try Tarte Park Ave Princess Matte Waterproof Bronzer ($29, Sephora). Place more bronzer, or a pink or peach blush, on the apples of cheeks. Then color lips with a neutral gloss to complete your sunlit look. For lasting lip color, try a stain such as Revlon Just Bitten Lipstain by ColorStay ($9, drugstores), and use the attached balm liberally.

Make the Move to Prime Time
Primer is the ultimate multitasker. Use it to fill in fine lines and keep makeup in place. If you tend to be oily, primer also acts as a blotter so skin stays shine-free all day, says Petra Strand, creator and founder of Pixi Cosmetics. Once a luxury pick, quality primers can now be found at drugstore prices. Try CoverGirl & Olay Simply Ageless Serum Primer ($14, drugstores; available this month). Apply primer over your moisturizer but underneath your makeup — or simply use primer in place of a lotion, says Molly Stern, a Los Angeles-based celebrity makeup artist: "It's not necessary to prime the entire face; you can also spot-apply to oily areas."

Shake Up Your Makeup
A single bold color choice can instantly give you a more modern look, and lets you have a little summer fun with your makeup. "Coral lips add a bright, youthful touch to your face," says Carmindy. Try Sally Hansen Natural Beauty Inspired by Carmindy Color Comfort Lip Color in Sunburst ($10, drugstores). Liners in teal and emerald are another trend worth trying this summer. "A new shade of eyeliner is the perfect and subtle way to look more current," says Strand. Apply the liner as close to lash roots as possible, then smudge with a cotton swab for a natural-looking line. Try Smashbox Jet Set Waterproof Eye Liner in Teal ($22, Ulta). Or consider a dalliance with a sparkling hot nail color, such as bright fuchsia Nicole by OPI Nail Lacquer in Nail Ya Azalea ($8, drugstores) — even if only on your toes. But to stay on the right side of the tasteful/overdone divide, don't try all three trends at once.

Give Limp Hair New Life
To make the most of humidity's plumping effects, but keep strands under control, start by spraying a volumizer at the roots of wet hair, suggests Ron King, celebrity stylist and owner of the Ron King Salon in Austin. Then apply a dollop of mousse the size of a golf ball from an inch below your roots all the way to the ends. Once hair is dry, mist it with a humidity-resistant hairspray, such as Garnier Fructis Style Full Control Non-Aerosol Anti-Humidity Hairspray ($4.11, drugstores).

Cue the Perfect Curls
For shapely ringlets without product-induced stickiness, Ron King recommends a combination of conditioner and gel. He squirts a little of each product onto a paper towel, folds the sheet so they blend together, then scrunches wet hair with the product side. "Squeezing the paper towel into your hair keeps the curls clumped together," says King. "Using bare hands can end up unfurling the curls." Once hair dries, gently break up the curls so they're not too stiff. Finish with a dab of silicone serum on any frayed ends. Try Samy Ultra-Lightweight Conditioning Serum ($5, Walgreens).

Pick a New Shampoo
Though sulfates in shampoo are good at whisking away dirt and product buildup, they can also strip color and shine. Two gentler options: sulfate-free Nature's Gate Organics Persimmon & Rose Geranium Color Protecting Shampoo ($8, natures-gate.com) and low-sulfate Tresemmé Naturals Nourishing Moisture Shampoo ($5, drugstores). Note: If you have thick hair that gets oily easily, a sulfate-free shampoo may not cleanse thoroughly enough for your liking, says stylist Louis Angelo of Garren NY in New York City.

Protect Your Color
Just like skin, unprotected hair will eventually show the ravages of sun exposure. "It's not always instant," says Angelo. "Your hair may look vibrant during the summer months because of the natural highlighting that occurs then, and become dull and lifeless by October." Leave-in hair conditioners with UV filters can help. Try a nongreasy spray such as Goldwell Sun Reflects Leave-In Protect Spray ($15, Ulta), which also adds a touch of shine. As with sunscreens for skin, reapply after swimming or every couple of hours.

Cut Drying Time
Blow-drying is the last thing you want to do during the dog days, but if you can't get away with air-drying, shortening your hot air exposure is key. Apply your styling products when hair is still wet, but not dripping. "Then do other tasks until hair is about 40 percent dry," says Patrick McIvor, Matrix artistic color director and owner of two Patrick McIvor Color studios in Pennsylvania. Once your hair starts to wave or curl, fire up your blow-dryer. If you don't start styling then, frizz may be tougher to tame.

Be Laissez-Hair by Night
If you have a short cut, slick it back with gel, or even conditioner, for a chic evening look. For longer hair, a smooth ponytail is perfect for summer nights, says Angelo. To add some extra interest, twist your ponytail into a knot and secure the base with a few bobby pins or a pretty barrette. Add a bohemian feel to any 'do and keep bangs off your face by braiding and pinning them to the side. A light gel, applied when hair is still damp, will help hold your style way past sunset. Try Fekkai Au Naturel Sheer Styling Gelée ($23, Nordstrom).

Shield Skin Post-Shower
Apply sunblock before getting dressed if you plan to spend time outdoors. Without the fear of messing up your clothes, you're likely to slather on more. (Remember, the recommended amount is an ounce — or shot glass-full — on your body, and a teaspoon on your face, ears, and neck.) "I usually apply a hydrating sunscreen lotion after showering, when my skin is still damp, so that I'm trapping in extra moisture and getting UV protection at the same time," says Heidi A. Waldorf, M.D., director of Laser and Cosmetic Dermatology at Mount Sinai Medical Center in New York City. One to try: Hawaiian Tropic Sheer Touch Crème Lotion SPF 50 ($10, drugstores).

Take Your Protection on the Road
After 80 minutes of UV exposure, swimming, or sweating, you're no longer fully protected by your sunscreen. To reapply speedily on the go, opt for a spray or wipe. Coat your skin until it has a slight sheen. (This may require two towelettes, depending on their size.) Try Dr. Dennis Gross Skincare Powerful Sun Protection SPF 30 Daily Sunscreen Towelettes ($18 for 20, dgskincare.com for stores).

Brush Up on SPF
Most women don't have time to wash their faces and reapply SPF and makeup during the day. Instead, brush a translucent UV-protective powder over your cosmetics. Bonus benefit: It will absorb summer's shine. Try E.L.F. Studio SPF 45 Sunscreen UVA/UVB Protection ($6, eyeslipsface.com). "Use a generous amount to get the advertised SPF," says Hadley King, M.D., a New York City dermatologist.

Don't Skip Your Scalp
The thinner your hair, the likelier your scalp is to burn when you're outside. Wearing a hat is your best defense, but second best is sunscreen. Look for a spray formulation that won't wreck your hairstyle, such as Nioxin Scalp Shield Sunblock SPF 20 ($13, nioxin.com for salons). Spritz some on your fingertips and rub it into any exposed areas — especially your part, says Jessica Wu, M.D., a Los Angeles dermatologist.

Get the Red Out
Quick relief for heat-related flushing, common in rosacea patients: Carry a frozen water bottle. "You can break a flush by holding the icy bottle next to the jugular vein on your neck, near the pulse point," says Dr. Waldorf. And swap thick, heat-trapping sunscreens for a new light liquid. Try SkinCeuticals Sheer Physical UV Defense SPF 50 ($30, skinceuticals.com).

Sop Up Slickness
Sweat and oil trapped between your skin and clothing (or the band of your sun hat) can lead to more chest, back, and forehead breakouts now. Help prevent them with oil-free makeup-removal wipes, such as Yes To Cucumbers Natural Glow Facial Towelettes ($6 for 30, Walgreens). Or, for breakout-prone skin, try salicylic acid-soaked Neutrogena Deep Clean Sport On-the-Go Cleansing Wipes ($7 for 18, drugstores).
